DISCUSSION
THE KBDI REMAINS ABOVE CRITICAL FIRE WEATHER THRESHOLDS IN CABO
ROJO AT 645. HOWEVER, IT CONTINUES BELOW CRITERIA IN GUANICA WITH
474 AND 353 IN CAMP SANTIAGO. TODAY, OVERALL BREEZY CONDITIONS
ARE EXPECTED ALONG COASTAL AREAS. WIND SPEEDS ARE EXPECTED TO PEAK
BETWEEN 13 AND 23 MPH AT TIMES, WITH STRONGER GUSTS DUE TO THE
SEA BREEZE. ALTHOUGH RH VALUES WILL DROP NEAR CRITICAL LEVELS AT
TIMES, THE AVAILABLE MOISTURE WILL MAINTAIN A LOW TO BRIEF
MODERATE FIRE DANGER RISK.
